STRUCT 
TID_AMPDU_TX(9)						     Internals						    STRUCT TID_AMPDU_TX(9)

NAME

       struct_tid_ampdu_tx - TID aggregation information (Tx).

SYNOPSIS

       struct tid_ampdu_tx {
	 struct rcu_head rcu_head;
	 struct timer_list session_timer;
	 struct timer_list addba_resp_timer;
	 struct sk_buff_head pending;
	 unsigned long state;
	 unsigned long last_tx;
	 u16 timeout;
	 u8 dialog_token;
	 u8 stop_initiator;
	 bool tx_stop;
	 u8 buf_size;
	 u16 failed_bar_ssn;
	 bool bar_pending;
       };

MEMBERS

       rcu_head
	   rcu head for freeing structure

       session_timer
	   check if we keep Tx-ing on the TID (by timeout value)

       addba_resp_timer
	   timer for peer's response to addba request

       pending
	   pending frames queue -- use sta's spinlock to protect

       state
	   session state (see above)

       last_tx
	   jiffies of last tx activity

       timeout
	   session timeout value to be filled in ADDBA requests

       dialog_token
	   dialog token for aggregation session

       stop_initiator
	   initiator of a session stop

       tx_stop
	   TX DelBA frame when stopping

       buf_size
	   reorder buffer size at receiver

       failed_bar_ssn
	   ssn of the last failed BAR tx attempt

       bar_pending
	   BAR needs to be re-sent

DESCRIPTION

       This structure's lifetime is managed by RCU, assignments to the array holding it must hold the aggregation mutex.

       The TX path can access it under RCU lock-free if, and only if, the state has the flag HT_AGG_STATE_OPERATIONAL set. Otherwise, the TX path
       must also acquire the spinlock and re-check the state, see comments in the tx code touching it.

NAME

       struct_ieee80211_channel - channel definition

SYNOPSIS

       struct ieee80211_channel {
	 enum ieee80211_band band;
	 u16 center_freq;
	 u16 hw_value;
	 u32 flags;
	 int max_antenna_gain;
	 int max_power;
	 int max_reg_power;
	 bool beacon_found;
	 u32 orig_flags;
	 int orig_mag;
	 int orig_mpwr;
	 enum nl80211_dfs_state dfs_state;
	 unsigned long dfs_state_entered;
       };

MEMBERS

       band
	   band this channel belongs to.

       center_freq
	   center frequency in MHz

       hw_value
	   hardware-specific value for the channel

       flags
	   channel flags from enum ieee80211_channel_flags.

       max_antenna_gain
	   maximum antenna gain in dBi

       max_power
	   maximum transmission power (in dBm)

       max_reg_power
	   maximum regulatory transmission power (in dBm)

       beacon_found
	   helper to regulatory code to indicate when a beacon has been found on this channel. Use regulatory_hint_found_beacon to enable this,
	   this is useful only on 5 GHz band.

       orig_flags
	   channel flags at registration time, used by regulatory code to support devices with additional restrictions

       orig_mag
	   internal use

       orig_mpwr
	   internal use

       dfs_state
	   current state of this channel. Only relevant if radar is required on this channel.

       dfs_state_entered
	   timestamp (jiffies) when the dfs state was entered.

DESCRIPTION

       This structure describes a single channel for use with cfg80211.
